Second opinion

: : Hi folks,
: : could I ask you these questions?
: : 1.The policemen were called in the prison to put out a fire.
: : (i think we should use "called to" here. is it right?)

: : 2.what does "to collect waiting dollars" mean?

: : 3.a high-paying job, and a high-paid job, which one is right?

: : 4.what is an "attitude barrier"?

: : 5.Could you tell me, these 2 words "back" and "home" in the
following sentence are of what parts of speech respectively?
: : Everyone back home will laugh at me if I leave China without
seeing the Great Wall.

: : 6.Clapp had a handheld device that could reveal objects below.
It showed ruins under the sand! He and his team started digging,
trying not to get their hopes (to succeed) up.
: : (what does "get up" mean here?)

: : 7.In a few years, a computer will be able to teach you English
and there will be no need for textbooks or teachers of English.
Instead of buying an exciting new textbook, the computer will ask
you to replace it with microprocessor one thousand nine hundred
and eighty-four. Texas Instruments is now working on this.
: : (why the author writes "1984" here?)

: : 8.The US continued to depend more on technology to prevent
fires. New
: : heaters and irons shut themselves off if they are tipped.
: : (what does tip mean?)

: : I would appreciate it enormously if you would help me!
: : Thank you for your attention.

: 1) The policemen were called TO the prison is correct, although
more usually the fire brigade would be called to put out a fire.

: 2) Not sure. Waiting is also what waiters and waitresses do -
they serve in restaurants, so maybe "waiting dollars" is payment
for this.

: 3) In the UK, we'd either say "high paying" or more probably
"highly paid".

: 4) I'd guess that an "attitude barrier" refers to a set of opinions
that someone may hold which prevents them from understanding or
doing something else.

: 5) This is a good question! I'd say that "back" is an adverb
and "home" is an adjective, but a case can be made for "back" being
an adjective and for "home" being a noun, or even for them both
being adverbs. Other opinions please!

: 6) To get one's hopes up is a standard English idiom, meaning
to become more hopeful. To "get up" in this sense means "to raise".

: 7) It's a humorous allusion to George Orwell's book "1984" that
dealt with the domination and misleading of the masses by the ruling
classes.

: 8) In the UK, we'd always say "tipped over", rather than just
"tipped". It means "knocked over".

#5: "Back," adverb. "Home," adjective.
"Everyone back home" means "everyone who is back home," in which
"home" is a predicate adjective and "back" modifies it.

#8: "Tipped" without "over" means "tilted," standing at an angle,
out of a vertical position.
